system failure occurs. For transactions on a single node, the database ensures ACID properties of transactions through Concurrency Control (two-phase blocking, two phase locking or multi-version, multiversioning) and recovery mechanism (log technology. For distributed transactions across multiple nodes, two-phase commit protocol (two phase commiting) is used to ensure ACID of transactions. It can be said that the database system is rapidly developing along with the needs of the financial indust
